New Report button in Outlook 2407 - How do i remove it?

I did some testing and think I have found the issue here. The "Monitor reported messages in Outlook" setting must be unchecked for the report shield to be removed. I am using KnowBe4 and completely removed the Microsoft report button from our organization's integrated apps. Then I configured the integration between KnowBe4 and Microsoft Defender. In order for this integration to work you need to have the "Monitor reported messages in Outlook" setting checked. I tested multiple machines and once changing this setting and bouncing outlook the report shield will appear if its checked and disappear if not. Microsoft this is causing a big issue for us. One option is to leave the setting checked and allow the integration to work but the report button will still show(You can remove it manually but this is not a solution for large scale operations). Two you can leave the setting unchecked and disable any reporting to Microsoft Defender which is also not a proper solution. Microsoft is there any plans to fix this issue? Currently we can not

have third party report buttons and still report messages to Defender. I hope this helps someone.

My teammate just talked to MS support about this issue. Response we got was:

Still a known issues on Microsoft's side of things with the report button. They are still working on a fix getting documentation and other published articles on it. Internally they can't share the exact status yet, but it is something they are working on. 

Typical Microsoft answer, I would say.

We are still seeing this issue in our tenant, too.

for everyone on this thread we found the root cause and will raise a fix on Monday. It should address the issue of user reported settings not hiding the inbuild report button on classic outlook for windows in coming weeks

thanks for bearing with us.

Is there any update on this? I still can see the report button in my Outlook even it should have been turned off from the settings.

Hi Dhairyya,

Thank you for your clear response which helped me understand what the future will eventually look like. Until then, we will try to minimize end user confusion with the reporting function. What do you think about this for our short-term plan?

Environment: all users use classic outlook on their windows 11 laptops and outlook mobile on their phones/tablets. 98% of mobile devices are running iOS and the other small group are android phone users. All users have been trained to report messages with an emphasis on phishing vs junk. Some like to report junk but not as important in the bigger picture. We run Defender for Business on all PC's and mobile devices.

Requirement: all windows/mobile clients need to have a consistent method to report messages

It would seem like the only option available to us would be to disable the built-in report button (the red outlined shield) in the Defender console under Settings, Email and collaboration, and User reported settings. In that section, we would disable the checkbox labeled Monitor reported messages in Outlook. Here is a screenshot:

Does this look correct to you? If not, what else should we consider?

On that same screen, there is an option to report messages within Teams. This is new to me so I wonder if we should enable it and let users know in case, they see something "phishy" in teams. Is this ok to have it enabled for end users to report within teams?

If these steps look good to you, our plan would be to continue to deploy the Report Message add-in via the main admin console, settings, and integrated apps. By deploying this add-in, it allows us to have the same Report Message button across all windows and outlook mobile clients.

And then sometime in the future, the built in Report button (red outlined shield) will be consistent across all platforms and clients, correct? If yes, do you have a best guess as to when this might happen? When it is stable and pervasive, we will then remove the Report Message add-in.

Hopefully, this all makes sense but if we are overlooking something, your opinion would mean a lot.

Thanks again for the guidance!
